Hi, today we have published the video of another single of John Option: You fill my soul. Of course the song is published under the terms of the Creative Commons License (CC-BY-SA) and it's completely produced only with free software: Ardour, Hydrogen, Jack, Qsynth, CALF, and many other great free audio software that we used under Debian GNU/Linux. Here you can listen the single: http://youtu.be/0hwTZgo808E As for the previous song we have done a little more in the direction of freedom and we published in our website[1] the single recording tracks and the complete Ardour session. All this material is published under the terms of the Creative Commons license Attribution Share alike so that anyone can use our tracks to produce a remix of our song or even a new song that have to be published under the same license.

JACK on Pi... almost working

by Ken Restivo

I was playing around with trying to use a Pi as a synth. So far so good except for two problems: 1) I've run into this: http://comments.gmane.org/gmane.comp.audio.jackit/26263 But I'm already using jackd2_1.9.8~dfsg.4+20120529git007cdc37-5+fixed1~raspbian1_armhf.deb which supposedly has Dbus removed/excised/banished/purged/kicked-to-the-curb. And yet, no dice, same error. Haven't had time to investigate it yet. I went back to jackd1 (wow, it's like it's 2007 all over again). 2) The sound coming out of either the built-in audio or an external C-Media USB interface is cracking and nasty, with obvious aliasing distortion. Any ideas why? I've tried 44.1k and 48k. No xruns tho, which is nice, at 44100/512/3 using jackd1 and fluidsynth. I've got it overclocked to 1Ghz, all is well with that (ran the self-test), and using the performance guv'na. I haven't tried with my FastTrack Pro yet because the Pi can't power it at the same time as a MIDI keyboard, and a working power cube for the keyboard has gone missing. The crackling/aliased sound is the big stumbling block though. Any ideas? -ken

Embertone Friedlander Violin on Linux - was Re: Recommended near-realistic strings section generator?

I'll trust the message that got my hopes up, hinting that Kontakt works on Wine. I decided to take the risk and bought the library. If all else fails, I can resort to my Windows partition, I guess (though I sincerely hope I won't need to do that. I really wanted to use this string library, and really wanted it to be on Linux :D ). Soon after the purchase, I got an email with the serial code, saying: > You can begin downloading right away. First, please install the latest > version of the Continuata Connect Download utility, our high-speed library > downloader, using the link below. > > http://continuata.net/download_app.php > > Just click the icon for your OS (PC or Mac - 64-bit OSX only). Once you've > downloaded and installed the Connect utility, run it and then copy-paste > your Download Code directly into the download code box, using the Paste > button. So, no download links. Using the app is really required... We have to install the app and paste the serial code into it, which it uses to identify and retrieve the file. I downloaded the Continuata Connect app and installed it through Wine. There was a "couldn't create directory" error at the end of the installation, but the program seems to run okay. I pasted the serial code into the program and it began downloading. The first file part went fine, but from the second part it decided to stop downloading every now and then, corrupting the file, then starting all over again. I don't know if that's supposed to be normal, but I don't believe it to be a Linux or Wine issue. Although I'm still stuck on the second file part, it seems it has chances of working, so I'll keep trying. If (no, "when") I get past the download issue, the next step is trying to install Kontakt Player. I'll post again when I have more news. PS: at the end of the email, they say: > If you can't install for whatever reason, get in touch and we'll get you up > and running as soon as humanly possible. I wonder if the "whatever reason" also includes "because I'm trying to run it on Linux", hahahaha :P. Jokes aside, if it indeed does work on Wine, letting them know might be a good idea too. -- ____________________ Blog: http://aiyumi.warpstar.net/

Re: [LAU] VJ / VeeJing software alternatives

2014-07-18 20:35 GMT+02:00 Michal Seta <mis(a)artengine.ca>: > Recently I stumbled upon this thing: > https://code.google.com/p/glmixer/ > > > > Michał > Had some time to try to compile it, and after a while I succeeded (inside Musix3=Debian Wheezy, and Ubuntu 12.04). Really good looking, the workflow is a little different from the normal kind of launch-sampler screens and such, but really interesting. If you are familiarized with tools that are present in video or image editors (Align, Crop, Stretch, Rotate) you get an idea of it to make some quick demos. The only problem is that after a while working with it, video-loops started to get stuck and if you restarted again GTmixer you got an error, and you had to restart session (or do some investigations to see what thread to kill to prevent this) to be able to work again on it. It perhaps is due to running it at the same time with some other audio programs and Jack, but not clear yet. Anyway, really interesting application.

General Audio question - soft recording and bad SNR?

by Oon-Ee Ng

Hi, I'm running Arch Linux 64-bit with jack2. I have a USB UA-25EX to which I connect a Shure SM75. I don't do much recording, and at a very amateur level for various volunteer projects. The maximum volume I get from my Shure SM75 seems very low. The result of this is when I normalize I get fairly significant background hum. Increasing the UA-25EX's gain just causes peaking at louder volumes, so no solution there. This happens with both Audacity and Ardour, so should not be software-related. Any suggestions as to what I should investigate? A bad mic (I did check, its not a knock-off)? Electrical noise from my laptop (used to use a different laptop but from the same manufacturer, same results from both). Jack settings?

VJ / VeeJing software alternatives

by Carlos sanchiavedraz

Hello dear all. Not long ago here there was a thread about video software and how it sucks or not. I wonder if any of you know a decent alternative for VJ software. It seems that LiVES should be some choice, but it's a little tricky and I don't see it has same workflow as others in the sense of launching video clips and such. There is also Freej, and Veejay but you have to compile it and it has client and server side. Here is an article about: http://linux.about.com/od/mediaplayers/a/Vj-Tools-For-Real-Time-Audio-Visua… Any suggestions or experiences? Thanks as always. -- C. sanchiavedraZ: * NEW / NUEVO: www.sanchiavedraZ.com * Musix GNU+Linux: www.musix.es

Testing VJPirate, Was:Re: VJ / VeeJing software alternatives

by Carlos sanchiavedraz

Hello again, Florent. (Keep the list on CC FWIW). I managed to guess the libraries needed to compile VJpirate with scons, as it says in the web, but I've come to a dead end, or so it seems. Maybe it rings a bell on you, It says something libxtract.h. No such file or directory" but can't find which lib is required for libxtract; nothing in repos related. Compiling info: " [...] Checking for fltk-config...yes scons: done reading SConscript files. scons: Building targets ... Compiling src/audio/AnalysisManager.o In file included from src/audio/AnalysisManager.cpp:24:0: src/audio/AnalysisManager.hpp:35:30: fatal error: xtract/libxtract.h: No such file or directory compilation terminated. scons: *** [src/audio/AnalysisManager.o] Error 1 scons: building terminated because of errors.

Sound Chip as a synthesizer on Linux. Thoughts, ideas?

by Fede

Hi all, I have a question on a topic not frequently addressed here, but why not just asking? Do any of you run some old sound blaster/adlib/gravis ultrasound card? I mean the ones with chip synthesizers. Just started reading a lot about the commodore 64's SID and just found out lot of my childhood's games actually run the audio on actual synths, which freaked me out totally. It would be nice to have any kind of synth chip running as a hardware synthesizer on a linux computer, really. In my country, the only PCI card with an OPL compatible chip is the YMF744b, which seems to be supported by ALSA. Getting that would mean starting to search for methods to create .o3 (instrument patches) files to be loaded to the card, for which there seems to be no dedicated native linux software. Maybe through DOSbox? Anyway. These are still just ideas, because the topic is very vast; there are lots of different sound chips, and I'm even considering getting a c64 to use it as a sort of assembler csound, if that makes sense. People familiar to the demoscene are aware of these kind of devices' powerfulness, but most of that that I've witnessed is tempered scale based and traditionaly rhythmically structured (and they really rock it that way), but it would be interesting (to me, anyway) to experiment creating sound textures and evolving timbres on these sort of hybrid soft-hard synths. *I might be missing lots of important details on the subject* So, do you people have any way to enlighten me on this? Any thoughts or ideas? Thanks a lot, really. Fede

Installing VJPirate error

by Kaza Kore

Florent. I tried to compile VJPirate and get his message. Originally had a missing fltk message but managed to work out what to install to clear that easily. This is more confusing to me though, as I know I have Jack and obviously I have ALSA.

RT kern for Raspberry Pi?

by Ken Restivo

Has anyone built one, i.e. off of latest Raspbian release, and made it available as a deb? For a while I thought about building one, but I kind of lost interest. Now feeling lazy and wondering if someone's already done it.
